    Agenda

  • Analog Video Optical transmitters modify signal output based on video content

    Modifications include amplitude (AM) or frequency (FM)

    Most commonly used for security and surveillance applications

    Tried and true technology and still the lowest cost option today

    80% + market share today for new installations

    Video Technology Overview

  • Analog Video Optical transmitters modify signal output based on video content

    Modifications include amplitude (AM) or frequency (FM)

    Most commonly used for security and surveillance applications

    Tried and true technology and still the lowest cost option today

    80% + market share today for new installations

    IP Video Video camera automatically encodes the video output into IP packets

    Video output can be transmitted directly over a traditional Ethernet LAN

    Power over Ethernet technology benefits

    Gaining popularity in security and surveillance applications

    Estimated to gain 50% + market share by 2010

    Video Technology Overview

  • Security video cameras offered in one of two formats: Analog video

    IP Video

    Analog or IP video camera functionality falls into two broad categories: Fixed

    Typically for entry doors, hallways, gates, etc.

    Pan-Tilt-Zoom (PTZ)

    Typically used in retail, casinos, etc. where the ability to change camera view is required and the cameras are actively monitored/controlled

    Video Technology Overview

  • 228 meter (750ft) distance limitationon coaxial cabling runs

    Typical Analog Video System

  • 100 meter (328ft) distance limitationon all UTP cabling runs

    Typical IP Video System

  • Ever increasing reach of surveillance Leading to quality, bandwidth, and transmission distance issues

    Beyond the reach of traditional copper (coax or UTP) cabling

    New camera locations may require new cabling

    Many IP camera installations co-exist with analog camera networks Cabling mismatch if upgrading cameras

    Extended reach of network beyond original design for new cameras

    Video Security & Surveillance Realities

  • Copper-based cabling limitations

    Limited transmission distances Coaxial cable < 228 meters (750 ft.)

    UTP cable < 100 meters (328 ft)

    Requires more equipment or signal conditioning / amplification to increase distance

    Susceptible to electrical interference Noise, high voltages and ground faults

    Quality and security risks Quality effected by distance and interference

    Copper-based cabling easy to tap into

  • Allows for extended transmission distances Multimode cable < 2km (1.24 miles)

    Single mode cable > 2km

    Smaller size, less weight and better tensile strength Easier installation when pulling through conduit or overhead cable trays

    Usually existing as network backbone in vertical risers and between buildings Reduce cost by utilizing existing fiber infrastructure

    Improve quality, bandwidth and distance of video system

    Fiber Cabling Benefits

  • High degree of security difficult to tap into or interfere with

    Immunity to electrical interference such as: Electromagnetic interference (EMI)

    Radio frequency interference (RFI)

    High voltage interference caused by:

    Fluorescent lights

    Card access door strikes

    Outdoor lighting systems

    Induced voltages caused by ground potential differences between locations

    Occurs in over 50% of all video security systems

    Fiber Cabling Benefits

  • Video Cabling Forecast

  • How to deploy fiber

    Deploy new devices with fiber ports Limited availability Expensive

    Copper-to-Fiber media converters Proven technology Allows the integration of fiber optic cabling in copper environments Successfully used in LANs and WANs

    Retail, Govt, Education, Enterprise, Service Providers, Industrial

  • A media converter provides a link between different types of media (or cabling) and

    operates transparently to the network

    Supported Media Types: UTP STP MM fiber SM fiber Coax

    What is Media Conversion Technology?

  • LAN Ethernet (10Mbps) Fast Ethernet (100Mbps) Ethernet & Fast Ethernet (10/100) Gigabit Ethernet (1000Mbps) Ethernet, Fast Ethernet, & Gigabit

    Ethernet (10/100/1000) 802.3ah support PoE CWDM

    TDM T1/E1 DS3 - T3/E3 POTS

    Serial RS232 and RS485 High Speed Serial

    Video Analog Video IP Video

    Supported Communication Environments

  • Benefits of Fiber Extend network distances Protect data from noise and interference Future proofing / bandwidth capacity

    Benefits of Media Conversion Protect investments in current hardware Flexibility: Add fiber on a port-by-port basis Save money

    Benefits of Media Conversion

  • Enterprise Application

  • Copper and Fiber can co-exist in most networks Most protocols support copper to fiber conversion Various form factors are available to fit any

    application Benefits of Media Conversion

    Extend Distance Reduce Electrical Interference Protect Investments Ease of Migration Save Money

  • IEEE 802.3af = Power over Ethernet (PoE) specification

    The ability of a device to transmit power as well as data on the UTP cabling link to an end device (15.4 watts)

    Typical end devices are IP cameras, wireless access points and IP phones

    IEEE 802.3at = Power over Ethernet Plus (PoE+) specification

    24 Watts

    More power for devices like PTZ IP Cameras

    Backwards compatible with 802.3af equipment

    IP Video andPower over Ethernet Technology

  • PoE greatly simplifies camera installation and is a huge benefit to IP network camera installations vs. analog equivalent

    No need for an electrician to install power receptacle in a difficult location

    Saves time and $$$

    Most IP cameras can be Powered Devices (PD) using PoE technology

    Switches can be Power Sourcing Equipment (PSE)

    PoE Injectors (also known as Midspan PSEs) simply insert power onto a CAT 5 Ethernet cable, without affecting the data.

    Media Converters can be Power Sourcing Equipment (PSE)

    PoE Media Converters, in addition to PoE Injectors, allow the addition of PoE capability to existing CAT 5 Networks while also converting from Fiber.

    Power over Ethernet Technology Enables IP Video

  • POE Network Switch

    100 meter (328ft) distance limitationon all UTP cabling runs

    Switch with port-selectable Power over Ethernet capability

    Typical IP Video System w/ PoE switch

  • 100 meter (328ft) distance limitationon all UTP cabling runs still applies

    PoE Injectors

    Typical IP Video System w/ PoE Injectors

  • Can the benefits of fiber be realized while still taking advantage of PoE? PoE media converters can provide the data link as well as inject the power

    onto the UTP inte
